Description
Technical field
The present invention relates to grain slag cooling water recirculation system sedimentation tank.
Background technology
At present, in smelting industry, grain slag melts liquid discharges from blast furnace grain slag mouth, and grain slag melts liquid and is cooled directly with water at grain slag mouth place and pours granulating pit with water by granulated slag groove, water in granulating pit flows into pond by water channel, and sewage pump extracts water transmission to the grain slag mouth in pond and continues on for grain slag cooling. this kind of water circulation has several drawbacks in that: one, in pond, the clay content of water gets more and more, the cooling effect of water declines, two, the conveyance conduit of cooling water recirculation system can because of in water clay content increase beginning gradually block, discharge is caused to reduce, water circulating effect declines, three, when both the above situation occurs, it is accomplished by supplementing new clear water and increases cooling effect, water consumption is caused to increase, too increase the water yield in water circulation system, if making the water capacity that the water yield exceedes water circulation system will result in sewage overflows, (otherwise processed bothers well) four, ability easy cleaning after the blast furnace blowing outs such as the mud precipitated in pond needs, but it is big to process one action amount for a long time, labor intensity is big, and the mud cleaning difficulty of pipe interior blocking is big. five, containing the lead silicate of certain ingredients in mud, during cleaning pond, need to release the sewage in pond, the lead silicate discharged along with sewage causes the wasting of resources, also increases the workload of the last treatment tank in smeltery. six, after tank drain, the mud of recovery is wet, concentrates accumulation to have water loss, bad process.
Summary of the invention
In order to overcome existing smelting enterprise to use the various problems that blast furnace grain slag blood circulation occurs, the present invention provides grain slag cooling water recirculation system sedimentation tank, use this grain slag cooling water recirculation system sedimentation tank, the amount of sludge of precipitation in pond can be reduced when blast furnace works, effectively reduce the clay content in sewage, alleviate pipeline stopping state, and mud can be carried out air-dry recovery simultaneously, the water flowed out in mud still enters in pond and recycles, add resource recycling rate, reduce the disposable treating capacity of the last sewage disposal system in smeltery, reduce labor intensity.
In order to achieve the above object, the technical solution adopted for the present invention to solve the technical problems is following design:
Sedimentation tank divides three grades by the degree of depth, and first stage precipitation tank is the deepest, and three grades of sedimentation tanks are the most shallow.Deep 3.6 meters of first stage precipitation tank pond, deep 3.3 meters of second-level settling pond pond, deep 3 meters of three grades of sedimentation tank ponds. Water channel one end is connected with granulating pit, the other end is connected with first stage precipitation tank, there is one-level connected entrance water channel and first stage precipitation tank junction, there are two grades of connected entrances the junction of first stage precipitation tank and second-level settling pond, three grades of connected entrances of the connectivity part of second-level settling pond and three grades of sedimentation tanks, one-level connected entrance is on the upper left side of first stage precipitation tank, two grades of connected entrances are in the lower right of first stage precipitation tank, three grades of connected entrances are in the lower left of second-level settling pond, all there is filter screen at all connected entrance places, one-level connected entrance filter screen order number is minimum, and three grades of connected entrance filter screen order numbers are maximum. First stage precipitation tank side has the air-dry pond of individual mud, the air-dry pond of mud to have a tank to lead to first stage precipitation tank, and there is filter screen the air-dry pond of mud and tank junction, bottom the air-dry pond of mud and bottom of gullet, becomes 1 ~ 3 degree of angle with ground, to the inclination of sedimentation tank direction.
The invention has the beneficial effects as follows: the amount of sludge of precipitation in pond can be reduced when blast furnace works, effectively reduce the clay content in sewage, alleviate pipeline stopping state, and mud can be carried out air-dry recovery simultaneously, the water flowed out in mud still enters in pond and recycles, add resource recycling rate, reduce the disposable treating capacity of the last sewage disposal system in smeltery, reduce labor intensity.
